I have a sample CSV file with the following contents:
$ cat SAMPLE.CSV
compid,active,tagno
-2147483646,1,"1"
-2147483645,0,"10000"
-2147483644,0,"1002"
-2147483127,1,"76245.1"
-2147483126,1,"76245.2"
-2147468087,1,"76245"
-2147466194,1,"1361B.2"
-2147466195,1,"1361B.1"
-2147466196,1,"1361B"
I want to sort by the third column called tagno
but I want it to respect the alphanumeric values in that column.
The desired result should look like this:
compid,active,tagno
-2147483646,1,"1"
-2147483644,0,"1002"
-2147466196,1,"1361B"
-2147466195,1,"1361B.1"
-2147466194,1,"1361B.2"
-2147483645,0,"10000"
-2147468087,1,"76245"
-2147483127,1,"76245.1"
-2147483126,1,"76245.2"
I've tried the following:
$ sort -t'"' -k2n SAMPLE.CSV
compid,active,tagno
-2147483646,1,"1"
-2147483644,0,"1002"
-2147466194,1,"1361B.2"
-2147466195,1,"1361B.1"
-2147466196,1,"1361B"
-2147483645,0,"10000"
-2147468087,1,"76245"
-2147483127,1,"76245.1"
-2147483126,1,"76245.2"
But you can see that 1361B
, 1361B.1
and 1361B.2
are almost reverse ordered.
